Trek Fuel+ MX 9.9 X0 AXS Gloss Navy Smoke: the pinnacle of the MX series

The Trek Fuel+ MX 9.9 X0 AXS is the most accomplished version of the Fuel+ MX: OCLV Mountain carbon frame, 60 Nm TQ HPR60 motor, 580 Wh battery, Bontrager Line Pro 30 carbon wheels, wireless SRAM X0 Eagle AXS drivetrain, 170 mm RockShox ZEB Ultimate fork and 150 mm of rear travel. Trek has not published a weight for this version; the Fuel+ MX 9.8 XT Di2, with an identical frame and drive system, serves as a benchmark at 19.79 kg in size M. The Gloss Navy Smoke/Matte Trek Black combines glossy smoky navy with matt black.

Who is it for?

For the demanding mountain biker who wants the best possible build on a lightweight e-MTB and rides enough to make the most of carbon wheels and high-end suspension.

The LVR workshop view

OCLV carbon, Trek's signature. OCLV is Trek's long-standing carbon know-how: moulding under pressure and heat that expels the air trapped between the plies and gives a dense, uniform material. For its mountain bikes, Trek offers it as OCLV Mountain, with reinforcements in the areas exposed to rocks and crashes. The Fuel+ MX 9.9 X0 AXS pairs this frame, covered by a lifetime warranty, with carbon wheels and a carbon cockpit, the most accomplished build in the MX series.

	Fuel+ (TQ HPR60)	Fuel EXe (TQ HPR50)	Rail+ (Bosch CX)
Assist	60 Nm, 350 W peak	50 Nm	Bosch Performance Line CX
Battery	580 Wh	360 Wh	800 Wh
Benchmark weight (M)	19.79 kg (MX 9.8 XT Di2)	18.68 kg (EXe 9.9 XX AXS)	23.98 kg (Rail+ 9.8)
Philosophy	Lightweight e-MTB, comfortable reserve	The most natural, shorter range	Power and a big battery

Put simply: the 9.9 X0 AXS is the best-equipped Fuel+ MX: Line Pro 30 carbon wheels, carbon handlebar, wireless derailleur, 170 mm RockShox ZEB Ultimate fork and Vivid Ultimate shock. Trek does not publish its weight; the closest benchmark remains the 9.8 XT Di2 at 19.79 kg in M.

The Line Pro 30 carbon wheels give precise steering: the bike follows the line you choose on off-camber sections and in hard-loaded corners. With the Assegai front tyre in MaxxGrip compound, the front end inspires confidence on the dusty rock slabs of the garrigue.

The SRAM X0 Eagle AXS T-Type drivetrain mounts directly to the UDH hanger, with no conventional derailleur hanger, and is controlled wirelessly; the 10-52 cassette offers a very low gear for short steep pitches. The TQ motor adds up to 350 W peak and cuts its assist at 25 km/h, with 250 W nominal, in line with the European e-bike standard.

Which Fuel+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Fuel+ EX 9.9 X0 AXS	TQ HPR60, 580 Wh	145 / 150 mm	Wireless SRAM X0 Eagle AXS	not disclosed
Fuel+ MX 9.8 XT Di2	TQ HPR60, 580 Wh	150 / 160 mm	Wireless Shimano XT Di2	19.79 kg
Fuel+ MX 9.9 X0 AXS	TQ HPR60, 580 Wh	150 / 170 mm	Wireless SRAM X0 Eagle AXS	not disclosed
Fuel+ LX 9.8 Eagle 90	TQ HPR60, 580 Wh	160 / 170 mm	SRAM Eagle 90 T-Type	20.88 kg

Our take: the 9.9 X0 AXS differs from the 9.8 Eagle 90, which shares its RockShox suspension, in its carbon wheels, carbon handlebar, Maven Silver brakes and wireless derailleur. Compared with the Fuel+ EX 9.9 X0 AXS (145 / 150 mm), it gains 5 mm at the rear and 20 mm up front.

LVR sizing advice

Between two sizes, the more compact one suits riders who like to play with the terrain, the larger one those looking for stability at high speed. The Fox Transfer NEO dropper goes from 150 mm in S to 175 mm in M and 200 mm from L upwards.

Your questions

Why is no weight published?	Trek does not publish it; the 9.8 XT Di2, with the same frame and motor, weighs 19.79 kg in M.
Are carbon wheels fragile?	No, they are designed for mountain biking; a check after a big impact is still a good habit.
Is the AXS drivetrain vulnerable to knocks?	The T-Type mounting on the UDH hanger does away with the fragile derailleur hanger.
Is the navy blue a gloss finish?	Yes, the smoky navy is glossy and contrasts with the matt black.

The LVR Cycles verdict

The best-equipped Fuel+ MX, with carbon wheels and handlebar, a wireless drivetrain and RockShox Ultimate suspension. The glossy smoky navy over matt black underlines its premium status.
